[PyKDE] Problem with dynamic tooltip

[stsao]

When I run the following code, I get a GPF.   This occurs with both PyQT 
2.5 and PyQt 3.0.
I am running Python 2.0 on Windows 2000 and PyQT was build using VC++ 6.0.

If you USE_DYNAMIC_TOOLTIP = false, then the code runs fine.  This code is 
basically a Python port of the example tooltip.cpp code shipped with Qt 
(which runs fine)

Can someone confirm that this indeed a problem and not just a local built 
error?

Thanks
